Length from tip of head to apices of folded forewings 9 mm ; maxillary palps each 2.00 mm long, 2nd segment slightly longer than 3rd, 5th about as long as first 4 segments together; labial palps each 0.97 mm long. Length of each forewing about 8 mm (n = 2); length of each hind wing 5 mm . Male genitalia ( Figs. 41–46 ): Abdominal segment IX longitudinally short, anterolaterally convex; dorsomedian keel triangular, granulose; anterior margin arched in dorsal view somewhat triangular; posterolateral lobe on each side triangular, setose, its setae in continuous curved line with those on posterior slope of keel. Deep U-shaped depression visible on dorsal margin in lateral view between segment IX and tergum X. Body of tergum X short, nearly quadrangular in lateral and dorsal views; apicoventral setose lobes forming pair of digitiform slender processes projecting posterad in lateral view, curved mesad in dorsal view. Dorsal interlobular gap oval, very large, between apicoventral processes. Inferior appendages each 2-segmented, basal segment long, slightly dilated distally, broad in lateral view; almost straight in ventral view; apical segment small, broad at base, curved mesad in ventral view and rounded apically. Phallic apparatus simple, base wider and curving slightly caudad; pair of broad and apically rounded subapical projections and apically rounded median subapical projection; endotheca broad with pair of rounded apical projections curved mesad and touching on midline. Material examined: INDIA : Sikkim : Geyzing , 2000 m , 19-ix-2009 , 2 males , Pandher & Parey , NPC . Uttarakhand : Kund , 1050 m , 11-vi-2009 , 18 males , 10 females , Pandher & Parey , NZC; Syanachatti , 1800 m , 27- ix-2008 , 4 males , 2 females , Pandher & Parey, NZC. Diagnosis: This species belongs to the Hydropsyche pluvialis Group. The male genitalia of Hydropsyche claviformis are quite similar to those of H. pluvialis Navás 1932 ( Vietnam ) and H. battos Malicky & Chantaramongkol 2000 ( Thailand ) . However, the well-developed triangular apical lobe and the broad and rounded apicoventral setose lobes of tergum X in dorsal view indicate that H. claviformis is a distinct species. Distribution: India : Sikkim .
